grigory [225]
The probability of getting a 2 or a getting a black card, find individual probabilities; 

A standard deck has 52 cards. 

There are 4 2's in a normal deck; probability of getting it is 4/25 

The probability of getting a black card is; 26/52 since half the deck is red and black. 

Now add up the probabilities since it says "or" 

(4/52)+(26/52)=30/52 probability of the card that you were dealt being a two or a black card.

What is the selling price of a $12,543 boat if a $758 discount is given?
Lelu [443]
Given:
Selling Price: 12,543
Discount: 758

We simply deduct the discount from the original price to get the discounted selling price.

12,543 - 758 = 11,785

The new selling price of the boat is $11,785.

Discount of $758 is 6% of the Original selling price.
758 / 12,543 = 0.06
0.06 x 100% = 6%

Sophie [7]

Answer:

3*( 8-2n)=5n

The number is 24/11

Step-by-step explanation:

three times

3*

the difference of eight and twice a number

3*( 8-2n)

is five times the number

3*( 8-2n)=5n

To solve

Distribute

3*8 -3*2n = 5n

24 -6n = 5n

Add 6n to each side

24 - 6n +6n = 5n +6n

24 = 11n

Divide each side by 11

24/11 = 11n/11

24/11 =n

The number is 24/11
